St_a_t_u_s_ Indicators----m----e
The power supply containsfive red LED indicators.When 
thesesLEDs
are on,they indicate that their corresponding power supply voltages
are operational.check out procedure for instructions for
for possible failure.
A red LED located near the cassette/music port is the system status
indicator.This indicator is turned on steady when power is applied
to the KSU.If the indicator flashes after power up, it could be
indicating a processor failure.Unplug and reconnect the AC power to
the power supply and observe the LED indication.If it still shows a
flashing indication, refer to Figure 
4-2.

Station Self Test
-----.- ---- -
The multiline stations can be self tested for proper operation per the
following instructions.
1.Disconnect the line cord at the station base.
IMPORTANT NOTE
THE ADJACENT ODD OK EVEN STATION WILL BE DISABLED DURING THE
TIME THAT THE STATION LINE CORD IS BEING DISCONNECTED OR
RECONNECTED.
2.Press and hold theMUTEkey Iand reconnect the line cord to the
station connector.The station will automatically perform a Self
test routine.
Release the
MUTEkey as soon as the test begins.
The sequence of the test is as follows:

Test the DSS/BLF Console for proper lamp operation per the following
procedure.
1.Disconnect the console line cord plug from the line.
2.Press and hold console key Cl0 while reconnecting the line cord

THE COMPANION STATION WILL BE DISABLED DURING THE TIME
THAT THE CONSOLE IS BEING DISCONNECTED AND RECONNECTED.
3.Release console key ClO,and note that the BLF indicators will
each turn on in sequence beginning with the station 10 indicator.
The indicatorswill then turn off and the console will 
become
operational.
Paired Stations

Station ports 10 through 41 are paired for data and for overload
protection as shown below.Console ports

IMI 66-047Maintenance
If erratic light indications or ring signals occur at a paired
station,an open data pair at either station may be the fault. A
station with an open data line may work properly on a short loop but
fail on a long loop.
Test the wiring of stations showing this symptom
per the checkout procedure given in Chapter 2.If a fault occurs which causes more than 300 ma. of current to be
drawn,the overload paired stations are disabled by circuit action.
Disconnect the disabled stations and reconnect them one at a time to
isolate the faulty one.
Failure Analysis----- ---- ___
KSU And Station
Figure 4-2 details a failure analysis flow chart to assist a service
technician in isolating a failure in a defective system.One way toisolate a failure is to substitute a known good assembly for a
suspected one.This is the recommended failure isolation method to
use with the system.
Connecting and disconnecting stations to the 
system does not affect
the stored station auto/speed dial memory data.This data is stored
in the KSU memory and not at the individual stations.Replacing the
KSU,however,causes all stored memory to be lost.This includes all
memory dialing numbers as well as all COS programming data.

DESK/WALL REVERSAL AND WALL MOUNTING
(22 Line/Feature 
Keyset and Single-Line Keyset, Only)
Conversion
--.----
To convert a station from a standard desk model to one which can be
hung on the wall,follow the procedure outlined below.
1.Remove and discard the pull out directory (22 Line/Feature Keyset,
only).
2.Remove the lower housing of the station, and rotate it 180
degrees.
w
The PWB contains circuitry which is sensitive to static
electricity discharge.
Be sure that your body and the
workplace are properly grounded to avoid any static
electricity discharge while performing the desk/wall
reversal.
3.Remove the knockouts from the desired mounting holes as
illustrated in Figure 4-3.
4.Replace the lower housing.Make sure that all wires are clear.
Wall Mounting
---- ---
Mount the station directly on the wall using two, 
#lo, panhead screws
(obtained locally),or mount it on a wall jack cover plate.
1.
2.
Thread the #lo screws into the wall within l/8-inch of the
surface.Refer to Figure 4-3 for the spacing dimensions.
Insure that the housing is converted properly for a wall mounting
installation (see above instructions).
3.
4.Pull out the latching lever.
Position the keyhole shaped holes in the bottom of the station
over the 
#lO screws or the cover plate studs.Slide the station
down until a slight click is felt.
5.Push the latching lever in to lock the station in place.
6.To remove the station,pull out the latching lever, lift to unsnap
both screws or studs from the bottom housing, and lift the 
station
away from the wall.
